Brain stem glioma is a distinct category of central nervous system tumor because of its unique location and behavior. The histology of brain stem gliomas spans the spectrum of gliomas located elsewhere in the central nervous system. The cause of these tumors is still unknown.
An infection caused by strep or staph bacteria can lead to toxic shock syndrome. These bacteria are common and usually don't cause problems. But in rare cases, the toxins enter the bloodstream and cause a severe immune reaction. This reaction causes the symptoms of TSS.
TSS is short hand for Toxic Shock Syndrome. It is an extremely rare (and usually preventable), but serious disease that can occur in men, women and children, sometimes resulting in death. It is mentioned in relation to tampons because some cases of TSS have been associated with the use of tampons and some scientific data suggests that the use of tampons increases the risk of TSS. However, tampons themselves have not been found to cause TSS.
